Another week in the NFL has meant another week of NFC dominance. The NFC East, which sent three teams to the playoffs last year, is dominating through the first four weeks. All four teams are in the top 10 of Imaginary Gridiron’s power rankings, and the Eagles are sure to rise once Brian Westbrook (ankle) is healthy.

The undefeated Bills and Titans are the class of the AFC thus far, while the Colts and Patriots look to re-gain their historical dominance coming off bye weeks. Both teams need to get healthy and address shortcomings in a hurry in order to contend for playoff berths.

For the lower half of the league, the Chiefs move up a few spots because of a stellar performance by Larry Johnson in a surprising win over previously unbeaten Denver. The Texans are still winless, but remain in front of the clearly inferior Raiders and Chiefs.

Once more divisional play begins, especially between teams from the NFC East, we will be due for a rankings shakeup. But for now, the Giants remain on top, at least until battles with the Cowboys, Redskins and Eagles threaten their pole position.
